5 re i device throng fmwlooking Fig. 2 is a. plan View of the vibrator head Wit-h the upper shell removed and a. portion of the applicator broken awo/y. Fi 3 is e sectional, elevation of the device loo ing toward the applicator. Fig. 4 is a detail View through i portion of the upper and lower shell'fshowing the means employed to lock the parteA together. Fig. 5 is a horizontal sectional View'7 through the same.

Referring now to the letters of reference placed upon the drawings :,-A denotes a tubular handle formed of wood, rubber, ,or other suitable material.

B indicates a chembered shell consisting of en upper portion B, land a lower portion B2 provided with an annular shank B3 sore ,-tlireeded to engage the handle A. The upper portion B is formed with an annuler rim 7J overlapping' the rim b of the iorion of ihe Shell which at suitable pointe throughout its circumference is indented at. b2 to receive :i projecting lug or off-eetportion b3 formed in the other half of the ehe/lly it being ehi/ions that When the heli of? the Shel? sprung into ennfent with the lower portion of the elA f i` the ings b3 will serve to lool; the parte together.

n is eonoentricnlly arranged within ihe portion B', and pivoted ai' c whereby it may he rotated with reepect thereto. The other part C2, is lodged within the portion B2 and pivoted thereto by means of the annular thirnhle e engaging the shank B3 of the outer shell.

c2 ports through the inner' shell l adapted to rogiSt-er with the ports o4 of the outer Shell i3.

C2 and C3 are projecting studs respectively' @ingrato/cd to the upper and lower portione of the shell C extending through slote formed in the wzill of the outer shell B, whereby the upper and lower port-ions of the inner ,shell may be rotated und the pasof air through the ports 54 and c2 regu* lated. or entirely out olf.

The inner shell C is preferably formed oit nngfhent Conducting inateriai.

indicates it resilient arm houeed Within ihe elnimhered shell and extending from side to side, one end being bolted thereto and the other supporting a tubular thimble D in turn supporting an annular bellshaped applicator D2 preferably formed ci soft rubber. y

5 E is a magnet, preferably formed with a laminated core E in turn secured to the -resilient arm D by means of a cot-ter pin or other engaging device.

F is the armature of the magnet .bolted at one end to the shell B.

G is a helical spring sleeved on a screwthreaded bolt G', in turn secured to the resilient arm D which extending through the chambered shell B is engaged by a thumbscrew or millednut G2, by adjusting which the tension of the spring Amay be increased and the magnet adjusted nearer to or farther away from its armature.

H is a cord leading up through lthe tubular handle A, carrying the conductors supplying potential to the magnet.

I is a rubber thimble sleeved on the cord H having a flange I adapted to bear against the end of the shank BB.

Having indicated the several parts by reference letters, the construction and operation of the device will be readily understood.

The device having been connected with a source of electrical energy, the thumb-screw G2 is rotated thereby adjusting the gap between the core of the magnet and thel armature F, as indicated in dotted lines in Fig. Z of the drawings-it being Well understood that. the degree of vibration given to the applicaV ,or D2 and that of the heat generated in the magnet will be in direct ratio with the distance between the magnet and armature.

If it is desired to use the applicator Without directing the air, inclosed Within the shell to the part being manipulated. (the temperature of which has been raised by the heat generated in the magnet) the inner shell C is adjusted by means of the projecting studs C2 and C3- until the air ports in the inner shell register with those in the outer shell; the air will then circulate through the device Without being directed.

toward the skin of the patient.

When [it .is desired to direct a warm current of air to the part being massaged, the inner shell is adjusted so as to close the air ports c2 and b, whereupon the only point of egress for the warm air contained within the shell will be out through the annular tube supporting the applicator. It will thus be seen` that the Warm air will be projected direct-ly to the part being massaged. The intensity of the vibration being increased or diminished' in accordance With the degree of adjustment given to `the magnet in the manner previously indicated.

Having thus described my invention, what I claim is sl. In a device A of the class described, a ltainberedV shell,
